Surface area=area needed to wrap a box
volume=amount of space in the box
surface area=2hl+2hw+2wl=2(hl+hw+wl)
volume=hlw
h=height
l=legnth
w=width
a. surface area is the outside area. lets say you have a cardboard cube and cut it on all the corners and edges so you ended up with 6 squares, the total areas of those squares is the surface area of the cube
volume is how much stuff can be put into the cube, we measure how many 1 by 1 by 1 cubes can fit into the object or how much water can fit in the cube
b. surface area is 2 dimentional since it is area and can be folded flat so the units would be square feet or square inches (ft^2, in^2)
volume is 3 dimentional since it is legnth width and height so it would be cubic foot, cubic inch (in^3, ft^3)
c. surface area=wrapping paper, wrapping stuff, painting an object
volume=how much water can fit in pool, how much punch to put in the jar to fill it up, which water bottle to bring so you have enough water
Answer:
![\sqrt[5]{x^2}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%5E2%7D)
and ![(\sqrt[5]{x} )^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B5%5D%7Bx%7D%20%29%5E2)
Step-by-step explanation:
They are both correct.
Answer:
(x + 7)(x - 7)
Step-by-step explanation:
We need to factor [ x² - 49 ]
The middle number is 0 and the last number is -49.
Factoring is when we fill in the blanks for [ (x + _)(x + _) ]
We need to know what goes in the blanks, we need to know:
- two numbers that add to get 0
- two number that multiplied together get -49
We can try 7 and -7.
7 + (-7) = 0
7 * (-7) = -49
This works, so fill in the blanks for the factor.
(x + 7)(x + (-7))
(x + 7)(x - 7)
Best of Luck!
Answer:
it would be -21-15g
Step-by-step explanation:
Answer:
1/10
Step-by-step explanation:
we multiply by the reciprocal when we work with fractions and division.
Now you just multiply across.
Therefore, you have 2/20, which simplifies to 1/10.
